Abstract
In real tokamak plasmas magnetic field deviates from the ideal equilibrium field. In typical situations the deviation of magnetic field from the equilibrium field is small. The magnetic perturbations may have a diverse nature: error fields produced by imperfect technical installation of poloidal and toroidal field coils, helical magnetic fields generated by MHD instabilities, magnetic fields created by external coils etc.

These inequalities can change the signs in plasmas with the Shafranov shift for magnetic surfaces whose radii \(\rho \) is less that the Shafranov shift \(\Delta (\rho )\).
